June 2022 sees the 70th anniversary of Queen Elizabeth II's accession to the throne. To celebrate this, posh London grocers Fortnum and Mason organised a competition to create a dessert for the celebratory meal. They had done the same 70 years previously to create a main course which resulted in Coronation Chicken. This is my attempt at making the winner, Platinum Pudding. It's a big lemony, almondy trifle and it's delicious.
